Domestic high-purity erucamide meets the urgent need of the market

January 03, 2023

The reporter learned from the Jiangxi Jinggangshan Technology Development Zone on November 24th that Jiangxi Weike Oil & Fat Chemical Co., Ltd. undertook the national innovation fund project - Clean Oil Production of High Purity Erucamide for Vegetable Oil Fatty Acids. The pilot test was successful and accepted by the Ministry of Science and Technology. The use of polyethylene and polypropylene introduced by large petrochemical enterprises such as Shanghai Petrochemical, Guangzhou Petrochemical, etc. indicates that the quality has reached the advanced level of similar foreign products, and can completely replace imports, and can be used in nonwovens, composite inks, thermoplastic powder coatings, and engineering. Plastics, thermoplastic elastomers and BOPP, CPP and other areas of application.
According to Wu Guilu, chief engineer of Jiangxi Weike Oil & Chemical Co., Ltd., the technology developer, they developed a new process unit for efficient distillation and short-range molecular distillation using vegetable oil by-produced fatty acids as raw materials, and separated and recovered palmitic acid, oleic acid and The erucic acid was extracted after the arachidonic acid and the erucic acid amide product was synthesized under the action of the autocatalyst RE-302B. The three-stage continuous separation and purification technology used in the new process to purify erucic acid amide can produce high-purity (≥ 99.0%) erucic amide, which is practically non-toxic and complies with EU RoHS Directive 2002/95/EC and post-correction Order requirements.
According to Wu Guilu, the current domestic production methods for high-purity erucic acid amides are erucic acid and ammonia reaction pathways, small-scale installations, low degree of continuous, high product costs, impurities, low purity (<92%), can not meet The introduction of large-scale polyethylene, polypropylene, BOPP film and non-woven fabrics and other devices on the use of lubricants.
High-purity erucic acid amide is an efficient and environment-friendly polymer functional additive, which plays an important role in the production of polyolefins, polyesters, polyamides and other plastics and non-wovens, and solvent-free powder coatings and resin inks. The high value-added bio-based biodegradable fine chemicals that are urgently needed in China have been listed in the high-tech fields supported by the country.
Wu Guixi told reporters that the high-purity erucic acid amide kit research and development project was funded by the Ministry of Science and Technology's SME Innovation Fund in 2006, and the product was listed as a national key new product. At present, Wolters Kluwer has used this technology to build an industrial production unit with an annual output of 3,000 tons.
